1. Replaces --crankshaft with --opt in tests.
2. Also fixes presubmit to check for --opt flag when
assertOptimized is used.
3. Updates testrunner/local/variants.py and
v8_foozie.py to use --opt flag.
This would mean, nooptimize variant means there are
no optimizations. Not even with %OptimizeFunctionOnNextCall.

Most callers passed kFinalizeIncrementalMarkingMask, so use that as
a default argument (not using default argument syntax to avoid including
heap.h in cctest.h).

The DescriptorInterceptor should intercept all
Object.getOwnPropertyDescriptor calls. This CL fixes
the interceptor's behavior if the iterator state is
ACCESS_CHECK.

Do not preinitialize the feedback vector slot if
the lookup iterator is an interceptor, because it is not
guaranteed that the iterator has a PropertyCell.
If the HandlerConfiguration has a non-masking
intercepting setter,
the iterator does not have a valid PropertyCell.

The property details of a LookupIterator are not accessible,

The mentioned asserts did not work properly with interpreted and turbofanned functions.
To fix this issue %GetOptimizationStatus() now returns a set of flags instead of a single value.
This CL also adds more helper functions to mjsunit, like isNeverOptimize(), isAlwaysOptimize(),
isOptimized(fun), etc.

Properties can be defined inside the object literal (ES6) or after
object creation. The behavior differes if there are accessors, interceptors
or proxies in the Object prototype chain.
These test cases assure we preserve correct behavior as we
improve performance of definitions in literals.

We used to intercept function definitions, but not declarations.
GenericNamedPropertySetterCallback now also intercepts function declarations.
For definitions, we call DeclareGlobal and then InitializeVarGlobal. For
declarations, we never call InitializeVarGlobal, thus we must check for
interceptors in DeclareGlobal.
If the semantics of a redeclaration are wrong, e.g., redeclaring a read-only
property, an exception is thrown independent of whether an interceptor is
installed. Usually, i.e., not during a declaration, we only throw if
the call is not successfully intercepted.

The existing PropertyQueryCallback intercepts getOwnPropertyDescriptor, but
it returns only value and attributes, not the accessors. This
PropertyDescriptorCallback returns a descriptor similar to Ecma-262 6.2.4.
You can either set a PropertyQueryCallback or a PropertyDescriptorCallback,
but not both. When you set a callback for DefineProperty(), you can set a
PropertyDescriptorCallback but not a PropertyQueryCallback.

With the Indexed/GenericNamedPropertyDefinerCallback it is possible to intercept Object.defineProperty() calls.
Requests that call JSReceiver::OrdinaryDefineOwnProperty() internally, also trigger the interceptor. This includes Object.freeze(), Object.preventExtensions(), and Object.seal().
As without this patch, the query interceptor triggers on
defineProperty, unless the definer callback
intercepts the request.

As a result LoadGlobalIC requires different slow stubs for each TypeofMode.
This CL is a prerequisite for not passing variable name to LoadGlobalIC:
the interceptor handler is the only kind of handler that requires a name
and therefore LoadGlobalIC dispatcher does not need a variable name as well.

The only right way to enable access checks is to install access check callbacks on an object template via v8::ObjectTemplate::SetAccessCheckCallbacks(). It does not make sense to enable access checks on an arbitrary object.
